The OHRDP has produced a little video showing how to use citric to prepare heroin injections. Remember to use as little citric as possible since it can be quite rough on the inside of one’s veins (burn, baby, burn!).

A lot of these packages of acidifiers – whether VitC or citric acid – ends up being used by folks to make their crack from cocaine powder. Which is alright, provided these smokers have access to good glass pipes.
